P2248R8 Enabling List-Initialization For Algorithms

[StephanTLavavej]

WG21-P2248R8 Enabling List-Initialization For Algorithms
WG21-P3217R0 Enabling List-Initialization For ranges::find_last
LWG-4444 Fix default template arguments for ranges::replace and ranges::replace_if

Feature-test macro ( ⚠️ renamed from the original proposal by cplusplus/draft@05e8bbe, thanks @cpplearner 😻 ):

#define __cpp_lib_algorithm_default_value_type 202403L

This was not further increased for WG21-P3217R0 (ranges::find_last).

Note: We're focused on implementing the remaining library-only features in C++23. Until that's done, we will NOT be accepting PRs for C++26 features.

Feature-test macro (expected - ⚠️ WG21 editors have raised concerns about its length and it may be renamed ⚠️):

#define __cpp_lib_default_template_type_for_algorithm_values 202403L

They renamed it to __cpp_lib_algorithm_default_value_type in cplusplus/draft@05e8bbe.
